MACHINE FOR USE IN MANUFACTURE OF SHOES.

Application filed March 30, 1925, Serial No. 19,347, and in Great Britain May 19, 1924.

granted on my application on February 5,.

1929. Machines of this type are especially designed for shaping or molding the heel end portion of the upper oil the last over a heel end form and also over an insole to which the molded heel end of the upper is fastened while on the form. It is to be understood, however, that the invention is not limited in its application to machines of this particular type, nor to machines for shaping an. upper over a form of the character lllustrated as distinguished, for example, from a last.

One important object of the invention is to provide conveniently operable and effective means adapted for use in machines of the above-mentioned type for tensioning an upper about a form. In one aspect, the invention thus has in view the holding of the upper against accidentaldisplacement while the operator has his hands lI'QO'tO adjust the upper materials relatively to the form in such manner as may be necessary to bring them into a proper n'edeterminetl position before they are. operated upon; and in another aspect the purpose is to assist in the shaping of the upper by drawing it tightly about the form before the shaping or molding pressure is applied. For the accom pllshment of these diilerent ends the construction shown comprises spring-operated means for tensioning the upper first lightly about the form while permitting it to be readily adjusted, and additional. means operable thereafter to subject the upper to increasedforward or lengthwise tension. For certain :purposes it is contemplated that prior to the shaping of the heel end of the upper, orthe assembling of the upper and the insolc,the toe end of the upper will have been previously molded substantially tothe shape desired for the finished shoe, and for i this class of work the invention further provides upper-tensiomng means constructed to take its tensiomng purchase'on the fore part of the upper without impairing the molding of the toe, the construction shown comprising a member shaped to hook under a molded inturned flange at the toe end of the upper and to abut against the inner face of the end of the molded toe, this member being shaped to conform substantially to the contour of that portion of the upper which it engages. An additional useful characteristic of this construction, which facilitates the proper positioning of the work and contributes to uniformity in the shaping of different uppers, is that the upper-pulling member by engagement with the inturned flange of the molded toe serves to support the forepart of the upper at a predetermined height relatively to the form which is invariable forall shoes of the same size and style.

Machines of the type illustrated in the above-mentioned Letters Patent comprise in their organization means for applying clamping pressure over the heel end of an insole on the form, for supporting the rear end portions of a welt shoe insole lip against the molding pressure on the upper, and for engaging the upper in jig holes formed therein to position it in predetermined relation to the form. I11 certain further aspects the present invention aims to provide improved means for engaging the heel end will be applicable to an organization having one or more of the above-mentioned characteristics. In one important aspect, the invention provides an insole-positioning device, adapted in the construction shown both to clamp the insole on the form and to support the rear end portions of the lip against the molding pressure, which device is movable with the form from; an upperreceiving position into position to present the work to the upper-shaping or molding means and. remains in operative position during a portion at least of the operation of laying the margin of the upper inwardly over the insole. In another aspect, the invention provides separate work-positioning devices 'or members arranged to bepositioned over the bottom, of the insole,- one, at-

a distance from the edge of the insole and the other over the margin of the insole, the latter member in the construction. shown being adapted to engage the inturned flange of a molded counter to position the counter in proper relation to the form whileelamping the counter flange and the margin of the, insole upon the bottom of the form and being movable out of operative position relatively to the other positioning member which, in the construction shown, is adapted to serve both as an insole-clamping member engaging the insole at a distance from its edge and as a lip support, as above described. Such movement 01"; the counter-positioning and clamping means out of operative position makes'way for the laying of the margin of the upper inwardly over the insole while the means which clamps the insole at a distance from its edge and supports the lip remains inoperative position. In a further aspect, the invention provides a novel organization of work-positioning devices including upper-positioning means movable into and out of operative position, the construction shown comprising upper-engaging jig pins which aremounted for movement away from the form with the device provided for applying clamping pressure over the margin V of the insole,

In, still anther aspect, the invention pro- Vides a novel'organization of" work-positioning means and mechanism for supporting or controlling said work-positioning means. the construction shown the. devices above describfidf for engaging and positioning the work atthe heel end are mounted to swing with the form from. work-receiving positi'on into position to present the work to. the upper-shaping means, and. there 1s provided means also movable with the form for moving said devices uhwardly from the tion, including a novel coi'istruction. and

arrangement of upper-jigging means and various novel details of construction and.

combinations oi parts, will now bc more particularly described by reference to the accon'ipanying. drawings pointed out in the claims.

The machine shown in the above-mentioned Letters Patent is a twin macl-iine (011).- two sets of operating instrumentalltles for operating respectively upon ri ht and left shoes, but only one of these sets o't instrumentalities need be and is herein shown for the purpose of an explanation of the present invention. For shaping or moldingthe heel end portion of the upper materials there is provided an inner heel end term 2 which is supported on a rod 4- mounted for lengthwise upward and downward movements in a form carrie 6, the latter being mounted for swinging movements on a pivot shaft 8 at the base oi. the machine, The form 2 provided with pins 10 which are fixed thereon and are arranged to project through holes formed. in the heel end portion of an insole to position, the. insole. in, exact predetermined relation to the form. Co-operating with the iorm 2 is upper-shaping means comprising a. heel band 12 within which. the form is carried by movement of its carrier (3 about the shaft 8, this movement being effected by a cam (not shown); which is mounted on a, cam shaft 1d and operates a lever 16 connected by means of a. lengthwise extensible link 18 to the carrier 6. It will be understood that after the insole and the upper materials have been mounted on the form 2 and have. been positioned in the manner more particularly hereinafter described, the machine is started, and the form 2 with the shoe materials thereon is carried rearwardly into the 1:2 and the latter is closed to shape. and clamp the upper about the form, the carrier 6 being locked in its rearward position by members which engage lugs 22 thereon. Thereafter wipers 24 are operated to wipe the upper materials inwardly over the insole and tacks are driven by means not herein shown to secure the materials to the insole. The. wipers are then retracted, the heel band is opened and the form carrier 6 is returned to its initial position to permit the work to be removed from the i'orm 2. These various parts and their operations are more fully shown and described in the Letters Patent mentioned.

For purposes of the present invention there is provided a novel construction and arrangement of worlii-positioning means cooperating with the form 2 comprising, as herein shown, means for jigging the upper relatively to the form, r01- elamping the heel end of a Welt shoe insole on the form and supporting the rear end portions of the insole lip against the inward pressure of the wipers, and for positioning a flanged counter relatively to the term. Upon the upper end of an am 26, hereinafter more particudepressed by a spring 36 which is mounted within the shank portion 34 and bears at its upper end upon the arm 26. To limit downward movement ot the member 32 and to prevent it from turning, there is provided a pin 38 which is fast on a s n-mg plateil) secured to the block and projects into a slot 42 formed in the shank 34C. The pin 38 has a knob 39 thereon by which the pin may lie-withdrawn from the slot 42 against the resistance voif' the spring plate to per mit differently shaped clamp members 32 to be utilized for different sizes ot' shoes, this being desirable in order that the member 32. may lie close to the insole lip a at the opposite sides of the insole to support the lip against the pressure of the wipers as they wipe the upper materials inwardly and shape them against'the ends of the lip in front of the heel seat, as described in the Letters Patentmentioned. It will be evident that thespring 36 tends to tip the block 30 about its pivot 28, such tipping movement being limited by engagement of the block with the arm 26, and this arrangement afiords provision for yield to permit the clamp member 82 to seat itself-evenly upon the insole. It will be understood thahto apply the member. 32 to the insole, the block 30 is carried downwardly by bodily move ment-of the arm 26, as more particularly hereinafter described, the spring 36 yielding to permit the block 30 to eontimie its movement after the member 32 has engaged the insole. The member 82 is provided with openings l iand it; to receive the ends of the pins 10.

Slidingly mounted also for vertical move ments on the block or support 30 is an ad-. ditional clamp member 48 which serves as a jig pin carrier and has mounted thereon a plurality of ig pins 50 for engaging the margi :al portion of the upper in holes previously formed therein to position the upper. Those jig pins may he tour in number, as in the machine of the earlier Letters Zatent, two being positioned for engagement with the upper at its rear end at opposite sides of the back seam, and two others for engaging it farther forwardly at the sidesof its heel end portion, although the invention is not limited to this particular number or pins. In the present construction the pins 50 are pivotally mounted on the member 4-8 and are curved about the axes of their swing, ig movements, so that when they are in position for engagement with. the upper they serve as books upon which the upper may be suspended with ample security against its displaceniient. Connected to each of the pivotally mounted j i g pins 50 gear sector 52 in engagement with racl: teeth 5% formed on the block 30. Springs 56 are mounted in the block 30 and hear at their lower ends against the member l8 to hold this member nori'nally in a position determined by its engagement with a ledge on the block 30. Vfheu the parts are in this relation the jig pins 50 are held in retracted positions, as illuijitrated in Figs. 7 and 8.

The member 4.3 is shaped, as illustrated in Figs. 1 and 8, so as partially to embrace the clamp member 32 at the rear of the insole lip, and it is thus adapted to press the lining and the inturned flange of", the molded counter, where such a counter is utilized, down upon the n'unigin of the insole and thereby to position the counter in proper relation to the form and the other shoe parts while also clamping the margin of the insole down upon the form. It will be understood that when the arm 26 is operated to move the block 30 downwardly toward the form 2, the member-3:2 first engages the insole, and thereafter the member l8 comes into engagement with the materials that lie over the margin of the insoleJ By continued downward movement of the block 30 after the member 48 has arrived in clamping position, the pins 50 are swung outwardly into position for the upper to be mounted thereon;

The arm 26, which car 'ies the block 30 and the parts supported thereby, is mounted to swing. laterally of the form 2 about a pivot shaft 62 which is mounted in a bracket 64:

projecting from a sleeve member 66 which serves as a support for, the arm. T he sleeve member (36 is mounted to slide upwardly and downwardly upon a guide rod 08 which is fast at its lowerend in a bracket mounted relatively to the form about the same axis and also to swing laterally of the form into or out of position over the bottom of the form. At its upper end the rod 68 is provided with a head 72 which embraces a stationaryguide member 7% to guide the rod in its movements about the shaft 8, and forward swinging movement of the rod is adjustably limited by means of a stop screw 76 which is mounted in a downwardly projecting end of the guiden'iember 74iand is arranged to engage the head '22 on the rod. By this means the position of the arm 26 relatively to the form carrier Omay be determined that when the arm is swung about its pivot 62 to carry the workpositioning devices over the form 2, the clamping members 32 and 4-8 will. be

properly positioned lengthwise of the form upper end of the arm. The arm isfurther guided and steadied in its swinging movements about the pivot 62 by means of a slidin connection betwen'the arm and the sleeve member 66 comprising a plate 8%- on the sleeve member and a co-operatmg plate on the arm, the plate 85 having a projection 8T whiea engages the plate 84 to limit swinging movement of the arm. After the arm 26 has been swung to carry the block 30 and the parts supported thereby into position overthe form, and as the supportingsleeve 66 is then moved downwardly 1n the manner hereinafter described the arm 26 is locked to the form carrier 0, both to assist in accurately alining the work-positioning means with the form and to cause this means to be swung rearwardly with the form carrier 6 the work is carried mto the heel band 12.

For this purpose the arm 26 is provided with a lug 80 having a hole formed therein to mally upheld by means of a spring which bears its lower end upon a. collar 92;

justably secured to the rod 68. For moving the sleeve member downwardly along the rod 68 to carry the work-positioning means on the arm 26 toward the insole-engaging bottom face of the form 2, the bracket 04 is connected by means of a link 9% to a treadle 96. For holding the member ('36 and the parts supported thereby against return upward movement, there is provided a clutch or retaining device comprising a friction clutch member 98 pivoted at 100 on the member 66 and arranged to engage a wear plate 102 fast on the rod (38. The clutch member 98 is secured adjustably to an arm 10% which is also pivoted at 100 on the member 66, this arm extending rearwardly and being engaged at its rear end by a spring plunger 106' mounted in a recess in the member 66-to hold the clutch member 98 in operative position. The member 98 thus permits the sleeve member 06 to be moved down wardly by the treadle 96, but locks it against return upward movement. In order to unlock the member 66 and permit it to move upwardly, it is necessary to swing the arm 104E about its pivot against the resistance of the spring plunger 106, and for this purpose the arm extends forwardly into position to be engaged by the foot of the operator in case it is desired to release the shoe materials and to rearrange them after the members 32 and %8 have been moved to clamping position. The machine is also provided, as more fully hereinafter explained, with automatic means for unlocking the sleeve member 06 in time relation to other operations, comprising a cam-controlled lever 108 which is pivotally mounted at 110 (Fig. I) and extends-into position under the rear end of the arm 10st (Fig.

At that time in the cycle of the machine when the sleeve member (56 and the parts supported thereby are returned to their uppermost positions and the arm 26 is released by the pin 88 to permit it to swing about its pivot (52, the sleeve member (56 and the rod 68 are swung forwardly about the shaft 8 by power-operated means comprising a bellcrank lever 112 (Fig. 1) provided with a. roll 1-14 which engages a wear plate 110 (Fig. 9) on the member (30, the bcll-crank being ope ated by a cam (not shown) on the cam shaft 14.

The machine herein shown is further provided, for purposes of the present invention, with means for engaging the upper and pull ing or tensioning it forwardly about the form 9., both to assist the operator in positioning and arranging the upper materials and to draw them tightly over the form before they are engaged by the heel band. As-h'erein illustrated the machine is designed for use on uppers that come to the machine eachwith its toe end portion already molded substantially to the shape desired for the finished shoe and having a flange 6 formed to lie over the margin of the insole, the flange herein shown comprising inturned and upturned portions for welt shoe work, and the upper pulling means is constructed to engage the molded toe end of the'upper without impairing-the melding of the toe. The construction shown comprises an upperengaging member 118 of spring steel which is curved to extend upwardly and rearwardly and then downwardly and forwardly under the molded flange 6 at the end of the toe and has its end face rounded to conform substantially to the curvature of the end face of the toe, as illustrated by dotted lines at 119 in Fig. 3. By reason of the shape of the member 118, only its extreme end portion,

curved as illustrated, has tensioning purchase on the upper, and since the member thus conforms substantially to the shape of that portion of the toe which it engages, and since it pulls substantially-along the median line of the upper, there is no danger of distorting the shape of the toe by the force of the pull. v

The member 118 .is mounted on a bracket 120 which is supported on a rod 122 formed on the uppere'nd of a lever 124. This lever carries a pin 126 which is slidablymounted in a slot 128 formed in a bracket or abutment 130 fast onthe form carrier 6. A spring 132 connected to the lower end of the lever 12 1 tends to swing the upper end of the lever forwardly about the fulcrum provided by the pin 126 and the bracket 130, the lever being further controlled by means of a hand lever 184, as more fully hereinafter de- I for limited turning movement of the bracket 120 about the rod 122, the bracket having thereon a pin 1 10' n'o'jectiug downwardly within a recess between two opposite stop screws 142 that are adjustably mounted in a collar 1 14.- adjustably secured on the rod 122. By reason of such turning movement of the bracket 120 the member 118 is permitted to accomodate itself to differences of swing of different uppers.

. The hand lever 134: is pivotally mounted upon the form carrier 6 and is shaped to embrace the lever 124. It has adjustably mounted thereon a pin 1 16 which is arranged to engage either one of two opposite cam faces 1 18 and 150 on the lever 12%, the cam face 150 being formed on a downwardly projecting hook portion 152 of the lever. Then the parts are in idle position the pm 146 may lie in a recess 154: in the lever 124,

being at this time below the projection 152,

so that by pushing on the member 118 the operator is enabled readily to swing the lever 124 rearwardly against the comparatively light resistance of the spring 132 far enough to permit the end of the member 118 to be readily hooked under the flange 6 of the molded toe of an upper. The spring 132 will then act on the lever124: to pull the upper materials forwardly about the form 2 under light tension sufficient to hold them from slipping downwardly over the form, while at the same time the member 118 by engagement with the inturned flange of the molded toe supports the forepart of the upper at a predetermined height relatively to the form, thus leaving'the operator free to position an insole on the form and to adjust the upper materials, including the countor and the lining, about the form and over the margin of the insole. After the upper materials have thus been arranged, and after the upper-j i gging and work-clamping means have been brought into operative position and the upper has been hung upon the jig pins 50, the lever 13% is moved upwardly by the operator and by engagement of the pin 1 16 with the cam face 150 the upper end of the lever 12d is swung forwardly to apply increased tension to the upper materials and thus to pull them tightly about the form before they are carried rearwardly into the heel baud. At the end of the upward movement of the lever 13 1 the pin 1 16 seats within a recess 156 above the cam face 150, so that the lever is held against downward movement when it is released by the operator. As the increased tension is thus applied to the upper by upward movement of the lever 13%, the lever 124 is forced bodily forward and may be swung to some extent about the point of engagement of the memher 118 with the upper and the pin 126 is carried away from the rear end of the slot 128, as illustrated infFig. 2, so that the lever 12 1- then fulcrums on the pin 146 instead of on the pin 126, and the effectivenesss of the spring 132 in its pull on the upper is increased by reason of the'increased leverage due to the shifting of the fulcrum point of the lever 12 1 nearer to the upper-engaging member 118.

In the operation of the machine, briefly summarized, the operator places the heel end iceturned to lie close to the rear. end portions of the insole lip, as shown in Figs. 6 and 7 and more iii detail in the earlier Letters Patent. Thereafter the operator swings the arm 26 to carry the upper-jigging and workclamping means over the form 2, and by de pression of the treadle 96 forces the insoleclamping and lip-supporting member 32 into engagement with the insole and the member 18 into positioning and'clamping engagement with the inturned flange of the counter over the margin of the heel end of the insoleat the rear of the insole lip, By continued downward movement ofthe support 30 the jig pins 50 are swung outwardly into operative position. If it should be observed at any time in these operations that the work is not clamped in proper position, the operator may depress the clutch controlling arm 10s by his foot and thus unlock the sleeve 66 and permit the upper-jigging and Work-clamping means to be retracted more or less from the form 2. When the materials have been properly clamped, the operator hangs the upper upon thejig pins 50 which enter the jig holes previously formed in the margin of the upper, as illustrated in Fig.6, and then slips the heel end of the upper.

downwardly about the form 2 enough to straighten it. The operator then raises the lever 134 to apply increased forward tension to the upper materials and tighten them over the form.

The shoe materials having been positioned relatively to the vform 2 and the upper tensioned about the form in the manner above described, the operator starts the machine, whereupon the form carrier 6, the uppertensioning means, and the upper-jigging and work-clamping means are swung rearwardly as a unit to carry the form 2 and theshoe materials into the heel band 12, and the heel hand is closed about the for-m2 to shape and clamp the upper materials against the end and sidefaces of the form. The camcontrolled leved 108 is then moved upwardly to unlock the sleeve member 66 from the rod 68 and thus cause the arm 26 and the supporting member 30 to rise far enough to withdraw the jig pins 50 from the upper and to removethe clamp member 18 from engagement with the shoe materials clear of the path of the Wipers, as illustrated in Fig. 7. The movement of the lever 108, however, is stopped at such a point as to cause the in sole-clamping, and lip-supporting member 32 to remain in engagement with the insole to.

serve as a support for the. insole lip against the pressure of the wipers, it being understood that the clutch member 98 immediately locks the sleeve 66 again as soon as it isreleased from the pressure of the lever 108. The wipers 24 are now operated to wipe the upper inwardly over the insole, as more fully described in the earlier-Letters Patent.

After the wipers have completed their overwiping operation, a further movement of the lever 108 finally releases the sleeve 66 and causes the arm 26 to be moved by the spring to its uppermost position, withdrawing the clamp member 32 from the insole, whereupon the arm is swung laterally away from the form by the action of the spring plunger 78. At this time also the lever 112 is operated to impart forward swinging, movement about the shaft 8 to the sleeve member 66 and the rod 68, thus making way for the tacking mechanism which is moved to operative position over the form and is operated to drive the upper fastening tacks, as also more fully described in the earlier Letters Patent. Al the tacking; is c01npleted, the form carrier 6 is swung forwardly by the lever 16, and the operator is then enabled, by downward movement of the lever 13 1 and by rearward swinging movement of the member 118, to release the upper and then to remove from the form the upper and insole unit now permanently secured together at the heel end.

Vhile the invention is herein described in its application to welt shoe work, it will be understood that in various novel and useful aspects it is not limited to that type of work.
